Abstract
A device for collecting, preserving and storing a sample of biological fluid comprising a porous medium for collecting and maintaining the membrane integrity of the eukaryotic cells contained in the sample, and their constituents is disclosed, the medium comprising at least 80% by weight of artificial components, advantageously at least 85%, preferably at least 90% of a total weight of the medium; and having a mean flow pore size (MFP) of at least 3 μm.
Claims18
A device for collecting, preserving and storing a sample of biological fluid, wherein the device comprises a porous nonwoven medium for collecting and maintaining the membrane integrity of the eukaryotic cells contained in the sample, and their constituents, the medium comprising at least 80% by weight of artificial components of a total weight of the medium, wherein the artificial components comprise semisynthetic fibers and/or synthetic fibers;
- wherein the medium has a mean flow pore size (MFP) of between 3 μm and 200 μm and a thickness between 100 μm and 2500 μm, and wherein the medium is sandwiched between two supports, the two supports being perforated opposite one another to allow the medium to appear.
